Unique Bargains 10mm Flex-Head 72 Teeth Box Ended Ratcheting Combination Wrench, CR-V Steel 2 Pack

Heat-treated chrome vanadium alloy steel drop forged body provides long life durability.
The surface is polished and electroplated with nickel and chromium treatment, high hardness and wear resistance, oil and water resistance, not easy to rust.
Smoothly pivoting through 180 degrees, the box end head holds any angle to slide onto fasteners.
The 12-Point box end provides strong gripping to tighten or loosen bolts without round-off, it won't slip even under high torque.
To prevent round-off, it contacts and applies force to the flat sides of fastener heads rather than the corners.
72 teeth mechanism allows you to work in the narrow space with the ratcheting movement as small as 5 degrees.
The open end is angled 15 degrees so the wrench can be flipped over with each rotation to engage the fastener twice as often in tight spaces.
